This Azure Defender PoC Series provides guidelines on how to perform a proof of concept for a specific Azure Defender plan. For a more holistic approach where you need to validate Azure Security Center and Azure Defender, please read How to Effectively Perform an Azure Security Center PoC article.

 

Planning

As part of your Azure Defender for Resource Manager PoC you need to identify the use case scenarios that you want to validate. A common scenario is cloud service discovery, where an adversary may try to enumerate the cloud services that are running via calls to Azure Resource Manager.

Since the enablement of this plan is performed on the Azure back end, it will not affect the performance of your workloads in Azure.

Keep in mind that you have 30 days free trial of Azure Defender for Resource Manager, which means that you should plan to execute your PoC prior to this expiration and based on the results keep it enabled or not.
